F-15C Eagle air superiority fighters have traditionally used APG-63 radars with mechanically steered arrays. While upgrades over the years have improved them, the mechanical steering components are a point of potential failure given the stresses put on them, and better radar technologies have appeared. With cruise missile defense rising in importance, and longer-range detection of threats desired, upgrades are necessary. They may also correct a known air-air weakness that can reputedly be exploited by aircraft like Russia's SU-30 family, though other reports claim that the mechanically-scanned APG-63v1s have also worked to close that hole. Thus far, 18 USAF F-15Cs have been modified to carry APG-63v2 radars – a misnomer, since the upgrade uses a revolutionary new AESA technology that bears little resemblance to its predecessor.
